New Dons signing Tomas Cerny admits he is a realist and is only at Pittodrie as back up to No.1 Joe Lewis.
The 33-year-old Czech Republic stopper has signed a one-year deal and will be on the bench tonight for the Euro clash with Burnley.
Dons boss Derek McInnes recently admitted securing a keeper before the UEFA registration deadline at 11pm last night was not a priority.
However, that changed following a knee injury sustained by keeper David Craddock in the Dons’ reserves’ 3-2 friendly win at Inverurie Locos on Monday evening.
Cerny was a free agent having left relegated Partick Thistle at the end of the season.
Cerny said: “I am realistic.
“Joe is arguably the best goalkeeper in the country at the moment and has had two brilliant seasons for Aberdeen.
“My role is to work Joe and push him as hard as I can in every training session to support him so that he can be at his best.
“However, at the same time to be 100% ready to step in if required and do my very best for the team.”
Following the injury to Craddock, the Dons needed goalkeeping back up as Danny Rogers joined St Mirren on a season-long loan.
Cerny spent three years at Partick and had five seasons at Hamilton from 2007-12 before joining CSKA Sofia.
Cerny said: “Everything happened very quickly and it was Tuesday afternoon at 5pm I was asked if I could make a medical for eight that night.
“I am really excited to be with Aberdeen as it is a great club.
“There was a couple of times when I was linked and was gutted when things didn’t work out but finally I am here so I am excited and happy.”
Cerny suffered relegation from the Premiership with Partick Thistle last year.
After his contract expired he opted to remain in Scotland.
He said: “I have a Scottish family, my wife is Scottish and our son was born here so I do feel half Scottish.
“As a family staying in Scotland was our preference.
“Aberdeen is a club with a great history and have been really successful under their current manager.
“It is a great opportunity to be here.
“It (relegation) still hurts as we had two very good seasons and finished top six in the second I was there.
“Everyone at the club was really excited and thought it would progress forward.
“But that last season didn’t work out at all and it is something that still hurts a lot.”
Cerny made 25 starts for Partick Thistle last season and has racked up more than 150 starts in the Scottish top flight with both Partick and Hamilton.
He said: “Things were a bit quiet over the last week or so with regards to potential moves.
“The decision to stay in Scotland really narrowed down the options of where I could sign.
“When that call (from Aberdeen) came it was out of the blue and very unexpected.
“I am absolutely delighted to be here.
“Burnley is a massive game for the club and it will be great to be part of it.”
